Medal Of Honor Settings Question

(1) I have a 9000 pro Radeon and a 22 inch flat screen. When I set the resolution greater than 800x600, then the game screen gets smaller than the total screen. Any way to make the game expand to fit the whole screen at higher resolutions?

(2) For some reason, my options/video settings are not being saved. I have to reset them every time I start the game. Anyone know what the problem is and how I can ensure my choices fro video settings are saved? I am running the game with the 1.13 patch.
